So assuming that the book is 100% the student has read 45% of the book so far in a time of 37 minutes so if you divide 45 by 37 you get 1 minute and 22 seconds per 1% of the assignment
If you multiply this by 100% you get 122 minutes for the total assignment
The Standard Deviation is a measure of how spread out numbers are. Standard deviation can be calculated by the expression as follows:
s = √∑(x - x(mean))^2/n-1
x(mean) = 24
s = √∑(x - 24)^2 / 7-1
<span>s = 6.11
Hope this answers the question. Have a nice day.</span>

Step-by-step explanation:

Answer:
64.
Step-by-step explanation:
Sigma notation is ∑48(1/4)^(n-1).
Upper limit = a1 / (1 - r) where a1 = initial population and r = common ratio.
So it is 48 / (1 - 1/4)
= 48 / 3/4
= 48 * 4/3
= 64.
